Objectives Banha-sasim-tang (BST), which consists of seven different herbs, is one of the most popular herbal formulae for treating gastrointestinal disorders in Eastern Asia. The commonly used herbal medicine is often co-administered with other therapeutic drugs, which raises the possibility of herb-drug interactions and may modify the clinical safety profile of therapeutic drugs. Methods We investigated the potential herb-drug interactions between BST extract and midazolam (MDZ) in mice. The area under the plasma concentration-time curve (AUC) of MDZ and 1'-hydroxymidazolam (1'-OH-MDZ) was evaluated for both oral and intraperitoneal administration of MDZ, following oral administration of BST (0.5 and 1 g/kg). Results It was found that the AUC of MDZ and 1'-OH-MDZ was lower in case of oral administration of MDZ. Administration of BST extract was not associated with hepatic cytochrome P450 activity. BST extract induced a strong reduction in pH and it has been reported that oral mucosal absorption of MDZ is lower at low pH. The decreased absorption rate of MDZ might be caused by the ingredients of BST and may not be related to other factors such as increased excretion of MDZ by P-glycoprotein. Conclusions The altered pharmacokinetics of midazolam caused by co-administration with BST in vivo could be attributed to a decrease in pH and subsequent reduction of MDZ absorption rate.

The purpose of this paper was to evaluate the effectiveness of a salt reduction education program. Subjects participating in this study were 251 employees (166 in the "educated" group, 85 in the "non-educated" group) at 8 hospital and industry food service operations in Daegu. After the salt reduction education program was carried out, a salty taste assessment of both groups was conducted. The educated group had statistically significant differences and the noneducated group did not have statistically significant differences. In terms of nutrition knowledge, while the nutrition knowledge of the educated group was increased (p < 0.001), that of the non-educated group rose at a rate of 0.92. In terms of dietary attitude, the educated group exhibited increased preference toward less salty foods when compared to the noneducated group (p < 0.001). Regarding dietary behavior, the score of the educated group was improved (p < 0.001), thereby indicating a preference for less salty taste. This means that nutrition education had influence on dietary behavior. However, after education, sodium excretion for the educated group was not significantly decreased, compared to before education. The results show that there was a positive correlation between salty taste assessment and dietary attitude and behavior for a high-salt diet. There was a positive relationship between attitude for a high-salt diet and sodium intake; when people prefere a more salty taste, they eat more sodium. Therefore, in order to change dietary preference away from salty taste and to decrease sodium intake, a nationwide, systematic and continuous salt reduction education program is needed.

It has been reported previously that 2,2-methylene bis(3,4,6-trichlorophenoxy acetic acid) (MTPA) is effective treating for clonorchiasis and less toxic to the hosts. In this studies the absorption, distribution and excretion of MTPA were observed. For this purpose $^{14}C-MTPA$ was synthesised from bis(2-hydroxy-3,5,6-trichlorophenoxyl) methan $^{14}C$ and administerd to the normal rabbit in a single dose of 10mg/kg IV or 20 mg/kg P.O. or to the Clonorchis infected rabbit in dose of 20 mg/kg/day for 6 days. Radioactivity in blood, tissue, bile, urine, feces and tissue of the fluke was measured after the drug was given. The concentration of MTPA in these samples were calcurated from the radioactivity. The result obtained as followes. 1. The increase in concentration of MTPA in blood and urine after oral administration of MTPA was so slow that the absorption of MTPA from the gastrointestinal tract appears very slow. 2. It is presumed that the excretion of MTPA also is slow because the reduction of MTPA concentration in blood after IV injection was very slow. 3. Large amount of MTPA was excreted from the bile. 4. During repeat dose of 20mg/kg/day for 6 days the concentration of MTPA in blood and tissue gradually increased. 5. The highest concentration of MTPA in the kidney and liver, heart, lung, spleen and muscle in decreasing order and the lowest concentration in the brain was noted. 6. During daily dose of 20 mg/kg of MTPA for 6 days of administration the concentration of MTPA gradually increased in urine and feces and the concentration of MTPA in feces was higher than of in urine. It appeares that MTPA take place enterophepatic circulation. 7. It is assumed that accumulation in large amount of MTPA in the liver and tissue of clonorchis, excretion of large amount from the bile is a favorable property of MTPA as a chemotherapeutic agent for clonorchiasis.

A recipe for diet kimchi containing 20% of sea tangle to Korean cabbage kimchi (SK) was developed for weight reduction purpose. The fermentation process of SK showed typical Lactobacillus sp. growth pattern like other kimchis. The effects of SK on weight reduction was studied in high fat diet (HFD) fed rats (n=40). Diet groups used for the animal study were HFD, HFD supplemented either with Korean cabbage kimchi used as experimental control (HCK), or with SK (HSK), or with J-kimchi (JK) which was purchased at market (FJK). The effect of kimchi on preventing obesity in rat fed HFD was found to be obvious by means of reducing visceral fat contents and improving serum lipid profiles through enhancing the lipid excretion in the feces (p<0.05). Leptin concentration of rat was significantly decreased by kimchi consumption (p<0.05). This result can be interpreted that adipocytes in these animals were fewer than that of HFD group. The plasma bililubin concentration was lower in kimchi group than HFD, meaning that returning bile from ileum to the liver was reduced. When the observe beneficial effects of kimchi on preventing obesity were compared among kimchi groups, SK only reduced the relative visceral fat contents significantly than other kimchi groups (p<0.05). Besides this, other parameters such as plasma lipid profiles, feces lipids, leptin, and bililubin concentration were not significantly different, even though the most beneficial effect on these parameters was observed from SK. In conclusion, long term consumption of SK seems to have a beneficial effect on the prevention of obesity through enhancing the excretion of lipids in the feces. The dietary fiber content of SK was increased by 7% compared to CK when 20% of sea tangle was added.

This study examined the effects of com gluten (CG) and its hydrolysate consumptions on weight reduction in rats fed a high-fat diet. Eight-month-old male Sprague-Dawley rats (n=40) were fed a high-fat diet (40% calorie as fat) for 4 weeks. They were then randomly divided into four groups and fed the isocaloric diets with different protein sources for 8 weeks. The protein sources were casein (control group), intact CG (CG group), CG hydrolysate A (CGHA group, 30% of protein as peptides and 70% as free amino acids) and CG hydrolysate P (CGHP group, 93% of protein as peptides and 7% as free amino acids). Body weight gain, adipose tissue weights, nitrogen balance, absorptions of energy, protein and fat, lipid profiles in plasma, liver and feces and hepatic activities of camitine palmitoyl transferase (CPT), fatty acid synthase (FAS), malic enzyme (ME) and glucose-6-phosphate dehydrogenase (G6PDH) were assessed. The CGHA diet had the highest amount of BCAAs, especially leucine, and most of them existed as free amino acid forms. The CGHA group showed significant weight reduction and negative nitrogen balance. Protein absorption and apparent protein digestibility in the CGHA group were significantly lower than those in other groups. Adipose tissue weights were the lowest in the CGHA group. Activity of CPT tended to be higher in the CGHA group than in other groups and those of FAS, ME and G6PDH were significantly lower in the CGHA group than in other groups. In conclusion, the CGHA diet which had relatively high amounts of free amino acids and BCAAs, especially leucine, had a weight reduction effect by lowering adipose tissue weight and the activities of FAS, ME and G6PDH in experimental animals, but it seemed to be a negative result induced by lowering protein absorption, increasing urinary nitrogen excretion and protein catabolism.
The present study was carried out to determine if Scutellaria balicalensis Georgi. extract (SBGE) exerts beneficial effect against the renal failure in rabbits. Rabbits were pretreated with SBGE orally for 7 days, followed by cisplatin injection (5 mg/kg, i.p.), cisplatin injection caused an increase in serum creatinine level, which was accompanied by a reduction in GFR. The fractional excretion of Na+, K+, glucose, and phosphate increased in cisplatin-treated animals, which was prevented by SBGE pretreatment. The uptake of p-aminohippurate, an organic anion, in renal cortical slices was inhibited by the administration of cisplatin, and the effect was prevented by SBGE. cisplatin injection increased lipid peroxidation, which was prevented by SBGE pretreatment. These results indicate that lipid peroxidation plays a critical role in cisplatin-induced acute renal failure. SBGE exerts the protective effect against acute renal failure induced by cisplatin, and its effect may be attributed to an antioxidant action.
Effects of kimchi lactic acid powder (KL) on weight reduction and lipid-lowering activities were studied using rats fed high fat diet. Spraque Dawley (40 rats) were fed 20% (w/w) high fat diet far 8 weeks to induce obesity and divided equally into normal diet (ND), high fat diet (HFD), and 10 and 20% KL-added groups. Body weight of HFD was 150% (p<0.01) of ND, while those of HFK10 and HFK20 decreased by 13 and 15% compared to HFD, respectively (p<0.01). Amounts of visceral fats for HFK10 and HFK20 were decreased by 42 and 48% compared to that of HFD (198% of ND), respectively (p<0.01). B had greater effect on reducing visceral fats than body weight. Plasma triglyceride (155%), cholesterol (129%), and LDL (161%) concentrations of HFD, which had been significantly increased compared to ND, dropped by 26, 9, and 8% (p<0.01) in HFK10, and 35, 17, and 33% (p<0.05) in HFK20, respectively. Decreased HDL by high fat diet was re-increased by KL supplementation. KL showed lipid-lowering and liver-protecting effects in liver possibly by interrupting lipid absorption in the intestine either by absorbing lipids in their cell walls or degrading them rapidly. Increased excretion of TG and cholesterol in feces of HFK10 and HFK20 indicates KL might have similar role to dietary fiber.

The nutrient digestibility, nitrogen balance and in vivo metabolizable energy supply of Mucuna pruriens whole pods fed to growing Pelibuey lambs was investigated. Eight Pelibuey sheep housed in metabolic crates were fed increasing levels of Mucuna pruriens pods: 0 (control), 100 (Mucuna100), 200 (Mucuna200) and 300 (Mucuna300) g/kg dry matter. A quadratic (p<0.002) effect was observed for dry matter (DM), neutral detergent fibre (aNDF), nitrogen (N) and gross energy (GE) intakes with higher intakes in the Mucuna100 and Mucuna200 treatments. Increasing M. pruriens in the diets had no effect (p>0.05) on DM and GE apparent digestibility (p<0.05). A linear reduction in N digestibility and N retention was observed with increasing mucuna pod level. This effect was accompanied by a quadratic effect (p<0.05) on fecal-N and N-balance which were higher in the Mucuna100 and Mucuna200 treatments. Urine-N excretion, GE retention and dietary estimated nutrient supply (metabolizable protein and metabolizable energy) were not affected (p>0.05). DM, N and GE apparent digestibility coefficient of M. pruriens whole pods obtained through multiple regression equations were 0.692, 0.457, 0.654 respectively. In vivo DE and ME content of mucuna whole pod were estimated in 11.0 and 9.7 MJ/kg DM. It was concluded that whole pods from M. pruriens did not affect nutrient utilization when included in an mixed diet up to 200 g/kg DM. This is the first in vivo estimation of mucuna whole pod ME value for ruminants.
A series of organosulfur compounds were synthesized with the aim of developing chemopreventive compounds active against hepatotoxicity and chemical carcinogesis. 2-(Allylthio) prazine (2-AP) was effective in inhibiting cytochrome P450 2E1-mediated catalytic activities and protein expression, and in inducing microsomal epoxide hydrolase and major glutathione S-transferases. 2-AP reduced the hepatotoxicity caused by toxicant sand elevated cellular GSH content. Development of skin tumors, pulmonary adenoma and aberrant crypt foci in colon by various chemical carcinogens was inhibited by 2-AP pretreatment. Anticarcinogenic effects of 2-AP at the stage of initiation of tumors were also observed in the aflatoxin B1 ($AFB_1$)-induced three-step medium-term hepatocarcinogenesis model. Reduction of $AFB_1$-DNA adduct by 2-AP appeared to result from the decreased formation of $AFB_1$-8,9-epoxide via suppression of cytochrome P450, while induction of GST 2-AP increases the excretion of glutathione-conjugated $AFB_1$ . 2-AP was a radioprotective agent effective against the lethal dose of total body irradiation and reduced radiation-induced injury in association with the elevation of detoxifying gene expression. 2-AP produces reactive oxygen species in vivo, which is not mediated with the thiol-dependent production of oxidants and that NF-KB activation is not involved in the induction of the detoxifying enzymes. the mechanism of chemoprotection by 2-AP may involve inhibition of the P450-mediated metabolic activation of chemical carcinogens and enhancement of electrophilic detoxification through induction of phase II detoxification enzymes which would facilitate the clearance of activated metabolites through conjugation reaction.

Since hepatocyte clearance, leading edge parencymal transit time and biliary excretion can be evaluated separately with hepatobiliary scan using $^{99m}Tc-DISIDA$, hepatobiliary scan may be useful in differentiating intrahepatic cholestasis from extrahepatic cholestasis. Excretory liver function was analysed in 13 healthy subjects and 11 patients with clinically suspected hepatocellular disease and 9 patients with extrahepatic biliary obstruction confirmed by surgery, radiological and clinical evidence. Indices of total liver activity (% TLA), liver parechymal uptake (% LPU), heart pool clearance (% HPC) and liver-heart rate (% LHR) were calculated from time activity curve over heart and liver. Compared with healthy subjects, significant reduction (p<0.05) in total liver activity (% TLA) and liver-heart rate (% LHR) was observed in all patients group. But no useful indices was demonstrated in differentiating hepatocellular disease from extrahepatic biliary obstruction.
